The invention relates to a junction insulated lateral MOSFET for high/low side switches. A p-conductive wall (4) ) between an n- conductive source zone (2) and an n-conductive drain zone (3), together with the source zone (2) and drain zone (3), extend to a p-conductive substrate ...
1. Choose N channel or P channel, in the low-voltage side switch, N channel MOSFET should be used, which is due to the consideration of the voltage required for the off or on-device. When the MOSFET is connected to the bus and the load is grounded, the high-voltage side switch is ...
Using N-channel devices as a high side switch necessitates a gate 2-20 drive circuit which is referenced to the source of the MOSFET. The driver must tolerate the violent voltage swings occurring during the switching transitions and drive the gate of the MOSFET above the positive supply rail ...
